seated in the saddle.
PEDALER FIT: This fit is for riders who are
comfortable pedaling. Typically, a child’s
second bike will be fitted like this.
Fit: rider is on tip toes of both feet while
seated in the saddle (toes of both feet
can touch the ground).
23
PRE-RIDE CHECK
Before each and every ride, be sure to check the following for the rider:
•
Make sure all bicycle components are tightened and free of debris.
•
Check air pressure in both tires (see page 31.)
•
Make sure the axle bolts/nuts or quick release fittings on the wheels are tight and
properly secured.
•
Make sure the saddle is properly positioned. Consult our bike fit guide on page 23.
•
Make sure the brakes are working. Rider should be able to operate the brakes easily
while seated. Make sure the rider understands how to use the brakes. All Prevelo pedal
bikes have front and rear handbrakes. The Alpha Zero has only a rear hand brake. The
Alpha One has an additional coaster (pedal) brake. Ask the rider to demonstrate the
ability to brake by starting and stopping several times in a safe location.
•
Make sure the rider’s helmet is secured properly (see page 25).
24
BASIC SAFETY
Riding a bike is fun! However, like any sport, bicycling involves risk of injury. By choosing
to ride a bicycle, or to put your child on a bicycle, you assume the responsibility for that
risk, so you need to know — and to practice — the rules of safe and responsible riding and
of proper use and maintenance. Proper use and maintenance of your bicycle reduces risk
of injury. We highly recommend adult supervision in the early stages of learning to ride,
especially in order to teach proper use and safety.
Because it is impossible to anticipate every situation or condition which can occur while
riding, this manual makes no representation about the safe use of the bicycle under all
conditions. There are risks associated with the use of any bicycle which cannot be predicted
or avoided, and which are the sole responsibility of the rider.
HELMETS. Your child must wear a helmet while riding a bike. Make sure to get a helmet
that fits properly and meets the latest Snell, ANSI or CPSC standard for helmets.
•
The helmet should fit snuggly and sit squarely on the head, sitting low (one or two
finger widths above the eyebrow), not tilted back.
•
Straps should be securely fastened under the chin (see your helmet owners manual).
•
Make sure your child understands that a bicycle helmet is only for riding bicycles.
A bicycle helmet should not be worn while playing, in play areas, on playground
equipment, while climbing trees, or at any time while not riding a bicycle.
CLOTHING. Your child should wear appropriate clothing while riding a bike.
•
Bright visible colors can help make your child more visible to drivers.
•
Avoid loose fitting long pants/skirts that may get caught in moving components.
•
Non-slip shoes are recommended and never ride barefoot.
•
Safety padding should not impede mobility.
ROAD CONDITIONS
•
Wet Weather: Impairs traction, visibility and braking. Ensure that your child understands
that the road can be slippery. Riding in wet weather, if necessary, should be done at
a slower speed and additional time should be allotted for braking. Apply the brakes
earlier and more gradually during these conditions.
•
Nighttime: Reflectors as well as front and rear lights are necessary to make your child
25
BASIC SAFETY
visible to drivers.
•
Traffic: Instruct your child to exercise the highest level of awareness of his/her
surroundings. It is important to never assume that a car driver sees a bicycle rider.
LIGHTS AND REFLECTORS. Reflectors are designed to pick-up and reflect street lights
and car lights in a way that makes the bicycle more visible to others. Check the reflectors
to make sure they are clean, straight, unbroken and securely mounted. Riding without
reflectors may reduce visibility to others. Reflectors are not a substitute for lights. If your
child rides at night, the bicycle must be equipped with lights.
WARNING: Riding after dusk without lights and reflectors is extremely dangerous. Certain
ordinances require lights and reflectors for night riding. Check your local laws.
EYE PROTECTION. Any kind of riding, but particularly off-road riding, involves airborne
bugs, dirt and other particles. Protective eyewear is recommended.
RIDING SAFETY
RULES of the ROAD. Children should be instructed on the rules of the road and appropriate
behavior and safety on streets.
•
Obey the rules of the road and all local traffic laws. In many areas children can
legally ride on sidewalks (check your local laws). Depending on pedestrian traffic on
sidewalks and the skill level of the child, sidewalks may be the safest place to ride.
•
Ride defensively…. look ahead, be ready for anything. Watch for parked car doors,
pedestrians, children playing, pot holes, sewer grates, railroad tracks, debris etc. and
assume that others, particularly motorists, do not see you.
•
Bicycles share the roads with motorists, pedestrians and other cyclists. Respect their
rights.
•
If bicycle lanes are available, ride in designated bicycle lanes. Ride as close to the
edge of the road as possible and in the direction of traffic flow or as directed by local
laws.
•
Stop at stop signs and obey traffic lights. Looks both ways before crossing
intersections.
26
BASIC SAFETY
•
Never ride with headphones. It is important for the rider to be able to hear the
environment around the rider (other cars, sirens). Loose wires from headphones, or
any other device, can become wrapped in moving parts of the bicycle and present a
hazard.
•
Never carry a passenger.
•
Prevelo bicycles are not designed to accommodate child carriers.
•
Do not carry anything which obstructs your vision or your complete control of the
bicycle, or which could become tangled or otherwise interfere with moving parts on the
bicycle.
•
Never hold onto a moving vehicle.
•
Don’t weave through traffic. Ride predictably.
•
Do not do stunts, wheelies, jumps or other advanced maneuvers. Parents and children
should think carefully before deciding to take the large risks that go with this kind of
riding.
•
If possible, avoid riding in bad weather, when visibility is obscured, at dawn, dusk or
in the dark, or when extremely tired. Each of these conditions increases the risk of
accident.
MOVING PARTS. Bicycles have moving parts that children need to be instructed not to
touch while moving. Wheel spokes, tires, chain, gears and other moving parts can cause
serious injury if touched while in motion. This hazard exists anytime the gears, pedals or
wheels are spinning or could spin, even if the bicycle is not in motion (for example, if the
wheels are spun when the bicycle is on a rack).
27
USE AND DESIGN
Prevelo Bikes have been specifically engineered for children, not adults. Be sure to reference
our online sizing guide to ensure a proper fit.
Prevelo Bikes are designed to be ridden on roads, paved or unpaved, as well as smooth
trails.
Prevelo Bikes are NOT designed for extreme riding including, but not limited to, jumping,
downhill or freeriding.
Normal wear and tear from proper use is to be expected. To keep your Prevelo Bike in great
shape, refer to the section on Maintenance and Care on page 29.
ANATOMY OF A BIKE
28
MAINTENANCE & CARE
FRAME. Prevelo frames are hand crafted from 6061 Aluminum Alloy requiring only minimal
care.
•
Wash using a soft sponge, diluted dishwashing soap and a bucket of warm water.
•
Note: If using a hose, choose a gentle spray as opposed to a harsh jet.
•
Dry with a clean cloth.
DRIVETRAIN
To Clean:
•
Use a soft-bristled brush to clean away any dirt or debris from the chain, derailleur and
cassette.
•
Spray bicycle chain cleaner/degreaser onto the chain, derailleur and cassette. Using a
rag, wipe clean while turning the crank.
•
Dry with a clean cloth.
To Lubricate:
•
Chain: Using only a bicycle chain lubricant, apply a drop to each link. Turn the crank a
few times to allow the lubricant to settle. Use a dry rag to remove any excess lubricant.
•
Derailleur: Using only a bicycle chain lubricant, apply a few drops onto the pullies only.
Use a dry rag to remove any excess lubricant.
BRAKES
Alpha Zero Brake:
The Alpha Zero is equipped with a rear V-Brake controlled by a hand brake lever. An adult
should perform regular checks on the operation and condition of the brakes to ensure
safety.
Check both brake pads to ensure they have not worn down past the wear lines. Replace
both pads at the same time.
Check for proper brake pad alignment. The pads should contact the rim without contacting
the tire.
Do not allow the brake pads to come into contact with oil or lubricant.
29
MAINTENANCE & CARE
Alpha One, Alpha Two, Alpha Three and Alpha Four Brakes:
The Alpha One, Alpha Two, Alpha Three and Alpha Four are equipped with front and rear
V-Brakes controlled by two hand brake levers. An adult should perform regular checks on
the operation and condition of the brakes to ensure safety.
•
Check all brake pads to ensure they have not worn down past the wear lines. Replace
all the pads at the same time.
•
Check for proper brake pad alignment. The pads should contact the rim without
contacting the tire.
•
Do not allow the brake pads to come into contact with oil or lubricant.
Zulu Three and Zulu Four Brakes:
The Zulu Three and Zulu Four are equipped with front and rear hydraulic disc brakes
controlled by two hand brake levers. An adult should perform regular checks on the
operation and condition of the brakes to ensure safety.
Check each brake assembly:
•
Proper alignment: the rotor should be centered in between the brake pads.
•
Full contact. Upon engaging the brake, each brake pad should make full contact with
the rotor.
•
Riding with improperly adjusted brakes, worn brake pads, or wheels on which the rim
wear mark is visible is dangerous and can result in serious injury or death.
•
All bolts on the brake assembly should be snug.
Check each brake lever and all hydraulic hoses to make sure there is no brake fluid leaking.
Check the rotors:
•
Each rotor should be clean and free of debris.
•
Each rotor should be straight and not bent.
•
All bolts should be snug so that each rotor is firmly attached to the wheel.
Note: Never squeeze the brake lever with the wheel removed. The brake pads may stick
together. If the pads get stuck together, very gently use a clean pad spreader tool to
separate the pads before replacing the wheel.
If you have any concerns regarding improper brake alignment, fluid leaks, function or wear
arise, please call (805) 557-8300, visit prevelobikes.com or visit your local bike shop.
30
MAINTENANCE & CARE
TIRES
•
Regularly check that air pressure matches the recommended PSI as labeled on the
sidewall of the tire.
•
Regularly inspect both tires for cracks, cuts, deterioration or uneven wear.
Compromised tires should be replaced immediately.
AIR FORKS (Zulu Three and Zulu Four)
•
Air/pressure: The weight/pressure chart is located on one of the fork legs. If you need
to check or adjust the fork pressure, you must use a shock pump available from bike
stores or online.
•
Rebound: Extreme rebound settings on your forks can adversely affect the handling
of your bike. If you have any questions about this please call (805) 557-8300, visit
prevelobikes.com/support or visit your local bike shop.
WHEEL QUICK RELEASE SYSTEM
•
WARNING: Riding with an improperly adjusted wheel quick release can allow the wheel
to wobble or disengage from the bicycle, causing damage to the bicycle and serious
injury to the rider. Therefore it is IMPORTANT that you:
•
Understand and apply the correct technique for clamping your wheel in place using the
wheel quick release.
•
Make sure that the quick release skewer nuts are positioned inside of the tabs at the
bottom of the fork dropout.
•
Make sure the quick release is securely closed before riding.
•
Each time you ride your bike, check that the wheel is securely clamped.
•
Refer to illustrations on pages 14 and 20.
•
Call (805) 557-8300, visit prevelobikes.com/support or visit your local bike shop to help
if you are unsure of how to properly install or remove the wheels.
